Hi fellow H3 owners,
this window problem just happened to me, It all started with doing a brake job, new calipers, rotors and . While I was working on the truck, I left the radio on and listened to my favorite music, for about a hour, . After finishing job I was ready to go for a test ride,.
The driver side window was stuck down, and all door locks would not work, all the other windows went up and down as they should, but still no drivers window, or door locks,! I checked all fuses, even #68 relay but still could not find problem, I drove 18 miles in 30 degree weather at nite, got home and was very confused with this truck.! The next day I took master control unit out of door disconnected all wires, cleaned pins etc, and put back together, also I took off positive and negative battery cables off battery, cleaned them , put them back on and tightened good, Well , I turned the key and everything worked,??? all good. windows worked, door locks worked, very happy with out come.
I went to dealer as this still did not make any sense to me, he told me that when the battery starts to get low in voltage the computers will sense some thing wrong and will start shutting down non-essential items in truck, drivers window and locks first, then other things like turn signals, driving lights, heater motor,!!! Man this truck has had me pulling my hair out, But still love my H3.
I hope this short story will help someone else who might have same trouble.
My girl friend has a H3 also, now I need to tackle her problem, no heater motor, no heat or AC. what next. I had this problem on mine so I know what it is, still a pain, and all computer related . Good luck all and good nite.
